Hotel Reservation

The application implements a hotel reservation service, build with Go and gRPC, and starting from the open-source project https://github.com/harlow/go-micro-services. The initial project is extended in several ways, including adding back-end in-memory and persistent databases, adding a recommender system for obtaining hotel recommendations, and adding the functionality to place a hotel reservation.

Supported actions:

• Get profile and rates of nearby hotels available during given time periods
• Recommend hotels based on user provided metrics
• Place reservations

Pre-requirements

• Docker
• Docker-compose
• luarocks (apt-get install luarocks)
• luasocket (luarocks install luasocket)

Running the social network application

Before you start

• Install Docker and Docker Compose.
• Make sure exposed ports in docker-compose files are available
• Consider which platform you want to use (docker-compose/openshift/kubernetes)
  • Build the required images using the proper method
    • In case of docker-compose => docker-compose build
    • In case of Openshift => run the build script according to the readme.
    • In case of kubernetes => run the build script according to the readme.

Running the containers

Docker-compose

• NOTLS: Start docker containers by running docker-compose up -d. All images will be pulled from Docker Hub.
• TLS: Start docker containers by running TLS=1 docker-compose up -d. All the gRPC communications will be protected by TLS.
• TLS with spcified ciphersuite: Start docker containers by running TLS=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 docker-compose up -d. The available cipher suite can be find at the file options.go.

Check if TLS is enabled or not: docker-compose logs <service> | grep TLS.

Openshift

Read the Readme file in Openshift directory.

Kubernetes

Read the Readme file in Kubernetes directory.
